Achilles tendon thickness, shape (spindle, parallel), echogenicity (heterogeneous, homogeneous) and Doppler flow (present or absent) were measured bilaterally with ultrasound.

Thirty-three (87%) tendons were parallel with homogeneous echogenicity, 3 (8%) were spindle shape and homogeneous echogenicity, 0 (0.0%) were parallel with heterogeneous echogenicity and 2 (5%) were spindle shape and heterogeneous echogenicity in the contemporary dancers. The tendon thickness, ROM, balance and endurence test were greater for the classical group. DFOS scores were greater for the contemporary group.

First, walking without poles (TW) followed by walking with trekking poles (PW), wearing surface electromyography (EMG) sensors recording muscle activation primarily on the paretic side. Inertial measurement units measured UL and LL kinematics, determining gait cycle (subphases: early support, mid-stance to mid swing, terminal swing). Principal component analysis verified muscle synergies.</div></div><div><h3>Results</h3><div>Trekking pole use did not elevate activation in the paretic UL (biceps or triceps brachii, TB), except for TB during pole-ground contact (mean difference<!--> <!-->=<!--> <!-->3.86, <em>P</em> <!--><<!--> <!-->0.001). However, it decreased muscle activation in the LL, particularly benefiting the GM muscle in the mid-stance to mid swing (mean difference<!--> <!-->=<!--> <!-->5.47, <em>P</em> <!--><<!--> <!-->0.001) and terminal swing (mean difference<!--> <!-->=<!--> <!-->5.26, <em>P</em> <!--><<!--> <!-->0.001). Muscle synergies remained consistent in both TW and PW.

Ils ont d’abord marché sans bâtons (MT), puis avec des bâtons de randonnée (MB), munis de capteurs d’électromyographie de surface (EMG) enregistrant l’activation musculaire principalement du côté parétique. Des unités de mesure inertielle ont mesuré la cinématique MS et MI, déterminant le cycle de marche (sous-phases : appui initial, de la mi-appui à la mi-oscillation, fin d’oscillation). L’analyse des composantes principales a permis de vérifier les synergies musculaires.</div></div><div><h3>Résultats</h3><div>L’utilisation des bâtons de randonnée n’ont pas augmenté l’activation dans le MS parétique (biceps ou triceps brachii [TB]), à l’exception du TB pendant le contact du bâton sur le sol (moyenne de la différence<!--> <!-->=<!--> <!-->3,86, <em>p</em> <!--><<!--> <!-->0,001). Cependant, la MB a diminué l’activation musculaire dans le LL, en particulier au profit du muscle GM entre la mi-phase d’appui et la mi-phase d’oscillation (moyenne de la différence<!--> <!-->=<!--> <!-->5,47 ; <em>p</em> <!--><<!--> <","PeriodicalId":21728,"journal":{"name":"Science & Sports","volume":"41 2","pages":"Pages 178-189"},"PeriodicalIF":1.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147552931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
